The Alpha Magnetic Spectrometer (AMS-02) is a space-borne particle physics experiment designed to measure with very high accuracy the composition of Cosmic Rays near Earth up to the TeV region, during a three-year mission on the International Space Station.

With a large acceptance (0.5 m²), an intense magnetic field from a 0.14 T magnet and a very efficient particle identification, AMS-02 will achieve a sensitivity to the existence of anti-Helium nuclei in the Cosmic Rays of one part in a billion, as well as provide important information on the origin of Dark Matter.

The Rome group is located at the Dipartimento di Fisica of Rome University La Sapienza and was responsible for:

• the design and construction of the Transition Radiation Detector gas system mechanical structure;
• the design and construction of the Star Tracker mechanical structure;
• the design and construction of the Transition Radiation Detector gas system electronics.

The launch of AMS-02 is scheduled for April 29th, 2011.
